摘　　要：针对区块链(block chain)生态系统为能源领域带来的新契机,初步研究了基于区块链技术的电动汽车(electric vehicle,EV)充电交易方案。在分析了区块链技术内涵、交易特征的基础上,提出建立基于雷电网络的电动汽车充电交易管理体系。借助智能合约与中介转账机制,建立了基于雷电网络的链下交易管理通道,并给出了电动汽车用户与充电桩进行链下交易的流程框架,该架构有助于减少链上交易压力,促进交易频率和交易速度的提升、降低区块链交易网络中的管理成本和运行风险等。结合充电桩使用场景,说明了基于雷电网络的交易方式与智能合约的实现过程。最后对区块链在能源交易管理方面的拓展性和可用性做了展望。In view of the new opportunity brought by block chain ecosystem to the energy field,this paper researches the transaction scheme of electric vehicle（ EV） charging. On the basis of analysis on block chain technical connotation and the characteristics of transaction,a management system of electric vehicle charging transaction based on raiden network is put forward. Through the use of smart contracts with intermediary transfer mechanism,the management channel of under-chain transaction based on raiden network is established,and gives the charging transactions between users and electric vehicles.This architecture can help reduce the transaction chain pressure,promote the transaction frequency,increase line speed,reduce management cost and operation risk in the block chain transaction network etc. Combined with the using scenario of charging piles,the process of transaction under the raiden network and the implementation process under the smart contract are explained. Finally,the expansibility and application of block chain in energy transaction management are prospected.
